In this Paper, we have proposed a new captcha based on digits and symbols. It is based on the facts that it is difficult for the machine to interpret symbols and perform the tasks accordingly from two different datasets. We have also pointed out the main anti-recognition and anti-segmentation features from previous works and implemented them on our proposed captcha. We have also presented here the pseudocode of it, have done a security analysis and usability survey to firm our claims regarding it. © 2015 IEEE.
